Migraine and the risk of glaucoma: a systematic review and meta-analysis.
Synthesis in Frontiers in neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Migraine and glaucoma are prevalent and burdensome conditions worldwide, yet the evidence linking them remains inconsistent. This systematic review and meta-analysis aimed to synthesize available evidence on their association and investigate sources of heterogeneity. Methods: We comprehensively searched PubMed, Embase, and the Cochrane Library from inception to April 8, 2026, for cohort, case-control, and cross-sectional studies examining the migraine-glaucoma link. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random-effects models. Heterogeneity was explored via subgroup, sensitivity, and meta-regression analyses. Study quality was assessed using the Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality checklist. Publication bias was evaluated via funnel plots, Egger's test, and trim-and-fill analysis. Results: Nineteen studies involving 3,625,071 participants were incorporated. The pooled analysis demonstrated a significant positive association between migraine and glaucoma risk (OR = 1.28, 95% CI: 1.20-1.37), with moderate heterogeneity (I Conclusion: This meta-analysis suggests migraine is associated with a significantly increased risk of glaucoma. While the association persisted directionally after adjusting for potential publication bias, its magnitude varied by data source, diagnostic method, and population characteristics. Further high-quality prospective studies employing standardized criteria are needed to elucidate causality and underlying mechanisms.
